. FRED UNGAR, on sAN FRANcIsco, CALIFORNIA AUTOMOBILE' BUMPER BRACKET AND AUXILIAR? s'IIooKv Ansonnnn Application filed September 18, 19281. Serial No. 306,766. l v'My 'invention relates to improvements in bearings 2 and lcarry heavy springs 8 'that automobile bumper brackets and auxiliary have their ends bearing against the rear bear- Y shock absorbers, and it consists in the c'omings 2 andthe collars 6. The springs may be binations, constructions and arrangements made to withstand any force desired such as, hereinafter described and claimed. for example, a force of 15,000 pounds. 55

An object of my invention is to provide an The front ends of the arms 4 arethreaded auxiliary'shock absorber that will withstand into supporting members 9, and these in turn a force of considerable morev strength than are connected to front supporting members is possible with the standard bumper. The by bolts 11. The bolts are ,spaced far 10 bumper withstands a compression strength of enough apart to receive a bumper 12. 60A

approximately 3500 pounds. The auxiliary The bumper 12 is designed to withstand a shock. absorberis designed to withstand a force of approximately 3500'pounds. If this pressure of 15,000 pounds. In this way the force of impact should be greater, it will movecar is protected far more effectively than is the bumper and the arms rearwardly. This 15 possible with the use of only a bumper. willcompress the springs 8 and, as already 65 I A further object'of my invention is to prostated, these springs will withstand a forcevide a device of the type described which is of far greater magnitude. The force of the extremely. simple in construction and which 'impact will be absorbed by the springs and is ldurable and e'iicient for the purpose iIinot bythe chassis. This will prevent the tended.

Other 'objects and advantages will appear vIn Figures 3 and '4 I show a slightly modif as the specification proceeds,- and the novel fied form of the device. -The arms 25 in this features will be particularlyl pointedvout in form of the device are straight.
